backbone - Computer Definition
The central or essential part of a network is commonly known as the backbone, or core.The backbone comprises very high capacity elements and subsystems such as transmission systems, multiplexers, switches, and routers. The term is used in the context of a wide area network (WAN), metropolitan area network (MAN), and local area network (LAN). See also core, LAN, MAN, and WAN.
The part of a network that handles the major traffic. It employs the highest-speed transmission paths in the network and may also run the longest distances. Smaller networks are attached to the backbone, and networks that directly connect to the end user or customer are called "access networks." A backbone can span a geographic area of any size from a single building to an office complex to an entire country. A backbone can also be as small as a backplane in a single cabinet. See collapsed backbone, backplane, core router, edge router and ISP.
